SCRAZPER ATTACHMENT FOR TORCHES.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed March 23, 1912. Serial No. 685,790.

To all whom it may concern:

Be it known that I, ALEXANDER WILSON, a citizen of the United States,residing at Clayton, in the county of Jefferson and State of New York,have invented certain new and useful Improvements in Scraper Attachmentsfor Torches; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The present invention relates to torches and scraping knives, andconsists in a device for detachably securing the scraping blade to thetorch in such manner that said blade is held at the proper angle withrespect to the torch flame and surface being scraped, to the end thatsuch surface may be uniformly cleaned.

The invention further proposes an attachment of the character inquestion, consisting in a clamping arrangement whereby the relativeangular positions of the torch burner and scraping blade may be variedat will; and which will permit of the scraping blade being readilyremoved, when necessary.

With these and other objects in view, the invention consists in thenovel details of construction and combinations of parts more fullyhereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspecification, in which like numerals designate like parts in all theviews :Figure 1 is a front elevational view.

of a torch equipped with the present invention. Fig. 2 is a top planview of the same, and Fig. 3 is a transverse sectional view of theclamping device.

Referring to the construction in detail, 1 designates the torch, havingthe usual handle 2 and burner 3; and 4: designates the blade of thescraper 5, which is used in connection with the heating flame of thetorch, after the usual manner. The blade 4 is adapted to be held at theproper angle with respect to the burner 3 through the medium of anadjustable clamping device, which is fully illustrated in the threefigures of the accompanying drawings. Said device consists in a ringcomprising two semi-cylindrical sections 6 and 7, connected to havetight frictional engagement with the torch 1 through the medium ofordinary screw bolts 8 and 9, that pass through enlargements 10 and 11formed at the respective ends of the ring sections 6 and 7 as indicatedin Fig. 2. The ring section 6 has formed integrally therewith a fixedjaw 12, which with the movable jaw 13 is adapted to clamp and hold inposition the blade 4 of the scraping tool, as shown. The jaw 13 ispivot-ally mounted on the jaw 12 through the medium of a pin 14 that hasbearing in the lugs 15, that are formed integrally with said fixed jaw12. The jaws for holding the blade 4; are adapted to clamp the bladetherebetween through the medium of a setting jaw 16, which hasscrew-threaded engagement in an extension 17 of the movable member 18,and which bears with frictional engagement against the inner face 18 ofthe fixed jaw 12 (see Fig. 3).

In order that the scraping edge of the blade 4 may be set and held atthe proper lateral positionwith respect to the heating flame, thesupporting clamp is constructed with an integrally formed and inwardlydisposed ledge 19, that projects from the fixed jaw member 12, and whenin applied position said ledge 19 rests upon the edge of the top 20 ofthe torch body, and in this position prevents the clamping ring 6 and 7)from the possibility of slipping downwardly on the torch, which wouldotherwise likely occur through constant use of the scraping tool. It isto be understood, of course, that any tendency to turn of the clampingring is prevented by tightening on the screw bolts 8 and 9 to therequired degree.

By holding the scraping tool to the heating torch, as herein shown anddescribed, it will be readily apparent to those skilled in the art thatpaint or other coating on a surface may be readily removed with aresult-ant v smooth surface, as distinct from being rough or chafed, aswould otherwise occur, were the scraping tool not held uniformly and atthe same angle with respect to the heating flame. And there is thefurther advantage that the heating and scraping of the surface may bedone in one and the same operation, and by substantially one and thesame tool.

It is obvious that those skilled in the art may vary the details ofconstruction and arrangement of parts without departing from the spiritof my invention, and there fore I do not wish to be limited to suchfeatures except as may be required by the claims.

What I claim is 1. The combination with a torch and scraper, of a devicefor holding said scraper on said torch and at the proper angle thereto;said device comprising a clamp holding the blade 01": said scraper andhaving frictional engagement with the torch body, and capable of havingangular adjustment thereon, and a member on said clamp engaging with thetop of the torch for the purpose set forth.

2. The combination With a torch and scraper, of a device for holdingsaid scraper on said torch and at tht proper angle thereto; said devicecomprising a clamping ring secured to the torch body, clamping jaws onsaid ring holding the scraper, and a proectin led 'e on one of said 'awsen a uw 1.
